seminiferous tubules and provide nutrition to germ cells
The epithelium of seminiferous tubule is made up of two types of cells -Sertoli cells and spermatogenic cells and spermatogenic cells. Sertoli cells are elongated and pyramidal which partially envelop the spermatogenic cells. These nourish spermatozoa, act as nurse cells for differentiating spermatozoa. These secrete a glycoprotein hormone, called inhibin which is involved in the negative feedback control of sperm production.
